project is on the surface tension of water and what affects the surface tension of water. The question that I am going to ask is how does temperature and salinity of water affect the surface tension of the water. My hypothesis is that the colder and the saltier that the water is‚ the stronger that the surface tension of the water will be. Some of the background research that I have done has explained to me that the surface tension of water is a property of a liquids surface that can cause it to

4D: Process information from secondary sources to investigate the relationship between the volumes of gases involved in reactions involving a metal and relate this to an understanding of the mole. METALS Reacting Gas Volumes AIM: to investigate the relationship between the volumes of gases involved in a reaction. HYPOTHESIS: A new gas will form when two gases will react together. BACKGROUND INFORMATION: Nitric oxide and oxygen are both colourless gases which do not dissolve in water

You may be wondering what diffusion‚ tonicity‚ osmosis and semipermeable membrane is. I’ll start off by explaining semipermeable membrane. A semipermeable membrane relates to the dialysis lab #1 because in dialysis tubing is considered semipermeable barriers. Semipermeable membrane is a membrane that allows passage of some particles but not others. (Lab manual) Diffusion on the other hand‚ is a form of passive transport where particles move down their concentration gradient from a region of high

The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the

Michelle Yeung Bio 101 Cyrus MacFoy June 16‚2015 Diffusion and Osmosis Exercise I. Molecules are always in constant movement. Molecular motion is a form of energy‚ the kinetic energy of molecules. The Brownian movement is the movement of small particles caused by the bombardment of the particles by millions of water molecule. This movement will continue indefinitely as long as there is water. My prediction for this lab is the solution of the water is hypertonic meaning there is a higher concentration

Experiment 6 Mole Ratio in a Chemical Reaction Background: Mole ratios of reactants are often times figured out by the use of the other products in a chemical equation. However‚ in the instance that the products’ mole ratios are unknown‚ it can be determined through the experiment. This method is called continuous variations. In this lab‚ I determined the mole ratio between Sodium Hypochlorite and Sodium Thiosulfate by using continuous variations of ratios in a given volume. This reaction was

traded in Africa. The trans-Saharan trade routes were a vast trade network that reached across the continent‚ on which diverse goods and resources were traded‚ and knowledge‚ ideas‚ and religion spread in a phenomenon known as cultural diffusion. Cultural diffusion that occurred along the trans-Saharan trade routes shaped the development of culture in medieval Africa. The trans-Saharan trade routes provided African people access to goods and resources that were not local to their
